Hi,
I’m using Xceed grid for an application that has a requirement to update around 1000 cells per second in a large grid (200 rows, 16 columns) . In an effort to improve performance and lower CPU usage I’m trying to minimize the number of screen repaints. Ideally I want to be able to control the number of screen repaints.
I’ve investigated SuspendLayout, but have come to the conclusion that this only gives a benefit when layout events are fired, and simply updating cells does not fire layout events.
Disabling redraws via the Win32 WM_SETREDRAW call causes the entire form to become unresponsive, and never correctly repaint itself even when refresh() is called. I suspect this is because the grid I’m using is too large.
I’ve tried Xceed.Grid.GridControl.BeginInit(), but didn’t notice any performance improvements. This is possibly because I’m not using a databinding, but updating the grid cells directly.
Can anyone point me in the right direction?
Cheers,
Adam.
